Hello,
I have a DIR-615 C1 configured as a gateway between a cable modem and a
switch.
Its purpose is to do better QoS than my cable modem is able to achieve.
This morning, under a load of ~10mbits I got this crash :

eth1 is the wan interface. I am running the 14.07 available on the openwrt
website. This was a full flash (not an upgrade).
I am available for further testing.
Thanks for your help
